Assessment
The BMW 3 serie 325D 204hp is a 3.0L turbocharged diesel engine producing 204 BHP and 430 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 300 BHP and 600 Nm — a gain of around 96 BHP (47%) and 170 Nm (40%).
This engine scores highly for remap suitability, with a balanced spread of gains across both power and torque — providing a noticeable improvement across the rev range. The tuning headroom is classified as high, based on the percentage gain available from the factory output.
From a technical perspective, the ECU is typically a Bosch EDC17 (likely), and the transmission is many variants use zf 5/6-speed automatics (where fitted); manuals also exist. at this torque level, transmission and driveline servicing history becomes especially important..
Considerations: High tuned torque: check transmission torque capacity and service history.. Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.
Fuel economy note: economy gains unlikely at full power; depends on driving style.
All figures shown are typical estimates based on aggregated Stage 1 data for this engine variant. Actual results depend on vehicle condition, mileage, and the chosen tuning method. We recommend discussing your specific vehicle with a qualified remap professional.
